Hello, I have a 4Runner 1990, manual 5 speeds. For a while now, when the car is cold, I do have hard times shifting the gears.. sometimes, can't shift at all if the engine is running. (I can when stopped).But if I drive a while like that, let say on the second gear, it gets easier to shift, eventually all shifting ok.. The clutch is 6 month old, the pedal bracket fixed, the fluid at maximum, no leeks there, and been purged in the summer. Any idea ?
thank you in advance for any suggestions.

If you cant shift with the engine running the clutch is not disengaging completely. To prove this turn your engine off and if it shifts easier then the input shaft has now stopped.

When you replaced the clutch, what did you do to the pressure plate? Did you replace it? Reface it? Nothing? What were the conditions of the fingers?

What was the condition of the shift fork? Did you replace the clutch or the shift fork or pressure plate with OEM components or did you go with an aftermarket clutch?

Try bleeding the clutch system again. It is possible there is still air in the line. Watch the mechanism while someone presses and releases the clutch. See if there is any give in the mechanism, like a weak shift fork or pedal bracket that gives.

Hello, and thank you for answering that fast.. impressive.
A garage did the clutch work, I did not supervise that. I don't know what condition is the fork on that. But they would have tell me if needed to change that too. Replacement was with Toyota piece, no aftermarket used piece.
I did, however purge the fluid, actualy, replace the fluid completely.. see I had this problem before, so I did first have the clutch fixed, then it happen again, the garage thought it was the hydrolic system itself (the joints inside) that were finished because of a wrong fluid put in before I got the truck. While verifying this, discovered that the pedal bracket plate was broken.. fixed that, and that fixed it all.. this was why I couldn't shift completely.

Anyway, I will bleed the clutch system again, like you said, might be air in the line. Thank you for your inputs. great forum.
Take care..

I doubt bleeding the line again will solve the problem, but it has to be checked. Let us know the result.

Yes, I know, will try the bleeding just to make sure. Why it is hard to say, is the fact that while the engine is cold, not used for a day or two, the shifting while runnig is hard or impossible, but once the engine is at temperature, and the car run let say 6 or 7 minutes, the shifting gets easier, almost back to normal. strange..
Sure will let you know what is found.

What kind of oil did they put in the transmission? This happened when someone put the wrong oil in the transmission of my MG.

Kim may be on to something. I noticed you live in Montreal (cold). Try draining the transmission and transfer case and putting in 75W90 gear oil (synthetic if possible). It may be related to the thickness of the oil you had put in in the summer.

Forgot about something else. Was the flex line replaced? The flex line deteriorates internally and can restrict the flow of fluid to the slave cylinder.

Hello everyone, thanks again for answering. I did put the car to the garage yesterday, so basicaly, there is some sort of "fork" right at the gear box level that action the shifting. This was completely gone, so it is replaced. now, while bleeding the line, the master cyl blocked, looks like the joints inside were gone as well, so no pressure. replacing this as well.
I get the truck back today, this should for sure fix my shifting problems.!
So there are the news. I will let you know monday how things went.!
take acre all, have agreat week-end.

Hello all, good monday ;!)
So, my 4Runner is now fixed. The problem was the master and slave cylinders for the line of the hydrolic clutch. Both pieces replaced, the were pretty "gone". All now is back to normal, shifting now a breeze, smooth..
Thanks again for your support.
Pascal.

Great! thanks for replying with what fixed your problem. I was curious.

Hello, I have a 1991 4Runner 5spd, manual tranny. It gradually got harder to shift, and now can't shift when running. The clutch doesn't fully disengage, and the pedal is pretty soft. I haven't checked the pedal mount plate yet, and don't want to take it in, unless I can't fix it. I think I'll try to bleed the lines and see if that helps. Any ideas? Thanks

I suggest you open a new topic instead of riding at the end of this one.
